`cpf-val` v3

[juliolmuller]

Version 3+ will be structured similarly yo the PHP and Python version of the packages:

• Main component should be object-oriented, so a class should wrap the logic of validating CNPJ.
• A CPF with repeated digits (e.g. 111.111.111-*, 222.222.222-*, 333.333.333-* and so on) is considered invalid (false)
• Create custom errors for ALL exepcted errors.
• Validate and parse arguments, when possible, and throw a custom TypeError.
• The following components are now expeced to be exported from the final bundle:
  • CpfValidator (base class)
  • cpfVal (should be a bound function of the isValid method of a default instance).
  • CpfValidatorTypeError (abstract)
  • CpfValidatorInputTypeError
  • CpfValidatorException (abstract)
• Update unit tests
• Update documentation
